Dermal Fillers
Medically reviewed by Dr. Patricia Sitnitsky, M.D. · Last reviewed July 2026
Avita MD provides dermal filler injections at our clinics in Los Altos, Mountain View, and Los Gatos. We use FDA-approved hyaluronic-acid fillers, including Juvederm and Restylane, to restore volume, smooth lines, enhance lips, and improve facial contours. An appointment takes about 30 to 45 minutes, results are immediate, and they last about 6 to 18 months depending on the product and area. Our providers take a conservative, anatomy-based approach to deliver results that look natural and proportional. Same-day appointments are available.
We are a physician-owned medical practice with more than 890+ five-star Google reviews. Because we are a full medical office, your provider understands your health history and can combine aesthetic treatments with medical care when appropriate.
How Dermal Fillers Work
As you age, your face naturally loses fat, collagen, and bone density. This creates hollows under the eyes, flattening of the cheeks, deepening of the lines around the nose and mouth, and thinning of the lips. Dermal fillers replace that lost volume with a smooth gel that integrates with your tissue.
The most commonly used fillers are made of hyaluronic acid, a substance your body produces naturally. We use FDA-approved hyaluronic-acid products such as Juvederm and Restylane. These fillers are safe, reversible, and available in different formulations designed for specific areas of the face. Thicker products provide structure and lift for the cheeks and jawline. Softer products are used for delicate areas like the lips and under-eye region. Because they are hyaluronic acid, they can be dissolved with hyaluronidase if reversal is ever needed.
Treatment Areas
Cheeks and Midface
Volume loss in the cheeks is one of the earliest signs of facial aging. Restoring cheek volume lifts the midface, reduces the appearance of nasolabial folds (smile lines), and creates a more youthful contour. Treatment is quick, with results visible immediately.
Under-Eye Hollows (Tear Troughs)
Dark circles and hollows under the eyes often result from volume loss rather than lack of sleep. Tear trough filler carefully placed beneath the skin can smooth this area and reduce the tired appearance. This is a delicate area that requires an experienced injector.
Nasolabial Folds and Marionette Lines
The lines that run from your nose to the corners of your mouth (nasolabial folds) and from the corners of your mouth downward (marionette lines) deepen with age. Filler can soften these lines for a more rested look.
Lips
Lip filler can add subtle volume, define the lip border, correct asymmetry, and smooth vertical lip lines. At Avita MD, we favor a gradual approach, adding volume in stages so the result looks proportional and natural. If you have never had lip filler, we start conservatively and let you decide if you want more at a follow-up.
Jawline and Chin
Filler along the jawline can create better definition, and chin filler can improve facial balance and profile. These are structural treatments that use firmer filler products designed to provide support and contour.
What to Expect During Treatment
Your visit begins with a consultation where your provider assesses your facial anatomy, discusses your goals, and recommends a treatment plan. If you decide to proceed, the treatment itself takes about 30 to 45 minutes depending on the areas being treated.
Most filler products contain lidocaine to reduce discomfort, and we can apply topical numbing cream before starting. You will see results immediately, with final results settling over a few days as any mild swelling resolves. Depending on the product and area, results last about 6 to 18 months. Mild bruising is possible and typically fades within a few days.
Combining Fillers with Other Treatments
Dermal fillers and Botox work well together. Botox relaxes muscles that cause dynamic wrinkles (forehead lines, crow's feet), while fillers restore volume and smooth static lines. Many patients at Avita MD do both in the same visit for a comprehensive refresh. For patients interested in skin rejuvenation, PRP therapy can complement filler treatments by improving skin texture and tone.

Frequently Asked Questions About Dermal Fillers
What are dermal fillers?
Dermal fillers are injectable gels, most commonly made of hyaluronic acid, that restore volume, smooth lines, and enhance facial contours. At Avita MD, we use FDA-approved fillers to address volume loss in the cheeks, under-eye hollows, nasolabial folds, lips, jawline, and other areas.
How long do dermal fillers last?
Depending on the product and treatment area, dermal fillers last six months to two years. Lip fillers typically last six to twelve months, while cheek and jawline fillers can last twelve to twenty-four months. Your Avita MD provider will explain expected duration based on your specific treatment.
Do dermal fillers hurt?
Most patients experience mild discomfort during filler injections. Many filler products contain lidocaine (a numbing agent) mixed into the gel. At Avita MD, we can also apply topical numbing cream before treatment. Most patients describe the sensation as pressure rather than pain.
What is the difference between Botox and dermal fillers?
Botox relaxes muscles to reduce dynamic wrinkles (lines from movement). Dermal fillers add volume to fill in static wrinkles, restore lost volume, and enhance contours. Many patients at Avita MD benefit from both treatments used together for a comprehensive result.
What is the recovery time after dermal fillers?
There is minimal downtime after filler injections. You may have mild swelling, redness, or bruising at the injection sites that resolves within a few days. Most patients at Avita MD return to normal activities immediately after treatment. We recommend avoiding intense exercise for 24 hours.
Can dermal fillers be reversed?
Hyaluronic acid fillers can be dissolved with an enzyme called hyaluronidase if needed. This is one of the safety advantages of hyaluronic acid-based products. At Avita MD, we always use a conservative approach, adding volume gradually so you can see results before deciding if you want more.
How long does a dermal filler appointment take?
A dermal filler appointment takes about 30 to 45 minutes, depending on how many areas are treated. Results are immediate, with final settling over a few days as any mild swelling resolves. At Avita MD, the visit includes a consultation to assess your facial anatomy and outline a plan before treatment.
Which dermal fillers does Avita MD use?
Avita MD uses FDA-approved hyaluronic-acid fillers, including Juvederm and Restylane. These products restore volume, smooth lines, and enhance contours, and they can be dissolved with hyaluronidase if reversal is ever needed. Your provider selects the formulation best suited to the area being treated.
